Thermo King has introduced a new hybrid electric-powered truck refrigeration system. A prototype of the system is being tested by Dean Foods, dairy processor and owner of one of the largest refrigerated direct-store delivery distribution networks.

According to the company, the new technology will help Dean Foods reduce its carbon footprint, while creating operational efficiencies and cost savings. Dean Foods is committed to removing 50,000 metric tons of carbon from its transportation system by 2013.

"Our highest priority is reducing the cost and improving the efficiency of our operations," said Harrald Kroeker, president of Dean Foods' Fresh Dairy Direct business unit. "Innovations that eliminate the use of diesel fuel, which is a major expenditure and our second largest source of emissions, drive cost savings to our business that benefit the environment."

"The commitment shown by Dean Foods and Thermo King demonstrates how corporations can use innovative technology to drive environmentally sustainable practices that increase business efficiency and have positive economic impacts," said U.S. Rep. Eddie Bernice Johnson of Texas, a member of the House Transportation & Infrastructure Committee and Energy & Environment Subcommittee of the Science & Technology Committee.

The electric-powered refrigeration units replace traditional mechanical models that rely on a separate diesel-powered engine to facilitate cooling while en route, and require oil, filters and anti-freeze as part of their routine maintenance. The new unit reduces emissions and waste, while also emitting less noise, Thermo King says.

The prototype truck refrigeration system has already been put into service in Dean Foods' Dallas-area fleet. The company aims to achieve at least a 50 percent savings in diesel fuel usage as compared to traditional refrigerated vehicles.

"This emission-reducing technology delivers superior functionality by offering fresh and frozen precise temperature management with complete flexibility for the management of fleets," said Dave Regnery, president of the Hussmann, Thermo King and Trane businesses in North America.

Thermo King is a business of Ingersoll Rand, which recently launched the Center for Energy, Efficiency and Sustainability (CEES), a global group of experts dedicated to integrating best practices for the long-term use of energy and other resources. Created by Ingersoll Rand as part of its worldwide commitment to environmental responsibility, this group develops solutions that advocate green policies, standards and education in the communities in which Ingersoll Rand operates and serves.
